New Consumer Unit Necessary?

Robert Garrett

We are having our conservatory replaced with a more substantial "garden room". The electricity in the conservatory was a spur off a current ring main, and the new room will be the same. The electrician says we must have the current consumer unit (which is plastic and has no RCDs being ~30 years old) replaced in order for the work to be certified. We had the system checked a few years ago and although advised a new consumer unit would be better, told it was not a legal requirement.

So do regulation require a new consumer unit with RCDs for this ring spur to be re-added, or is he being over cautious?

    It was my assumption that "just" extending the current ring as it already was extended would be okay but the electrician is adamant that this could not be certified. Hence the questions. I am awaiting his quote to replace the box.

    Is there a fused spur at that point that isolates the compete conservatory  or does the ring loop out and back in again ?
    Even so, any new wiring needs cover from an RCD, but the RCD does not have to be in the main consumer unit - though it usually is.

    Or are retrofit RCDs available for the existing box ?
